  1. Make a round 89.5 + 0.5 mm (3.52 + 0.02 in) hole in the process wall. Install the cooling set horizontally whenever possible to ensure the best possible cooling performance.
  2. If the process wall is more than 125 mm (4.92 in) thick, weld a lengthening piece (max. 50 mm (1.97 in)) to the mounting tube.
  3. Weld the tube of the mounting flange tightly to the inner metal plate of the process wall.
  4. Attach the cooling set to the mounting flange and use a 5-mm Allen key to tighten the mounting screws. Proper tightening of the mounting screws is important for good thermal contact.
  5. If the process chamber is in use or otherwise warmer than ambient temperature, let the cooling set warm up before inserting the probe to avoid condensation:
    1. Plug the hole of the cooling bar tightly with the plug that is attached to the cooling set.
    2. If installation of the cooling fins is required, attach them at this point to let them warm up as well. See 9.
    3. Wait for a few hours.
    4. Unplug the cooling bar and continue the installation.
  6. Use a 2-mm Allen key to loosen the locking screws on the cooling bar.
  7. Push the probe head into the cooling bar until it meets the other end and cannot be pushed farther. Approximately 7.5 cm (2.95 in) of the probe head will remain outside the cooling bar.
    CAUTION Do not push or pull from the probe cable.
  8. Tighten the locking screws to lock the probe head in place.
  9. If installation of cooling fins is required, attach them around the cooling bar using a 5-mm Allen key. Place the cooling fins so that the locking screws are not obstructed. Tighten the two mounting screws so that the fins have good thermal contact with the cooling bar.
